I love the game of baseball, so spring training is like Christmas for me. I grew up in Arizona so I have been to just about every spring training venue in the state. Surprise Stadium is definitely one of the nicest and well maintained. The thing about this stadium is that it faces a northeast direction, which is key when it comes to shade. Shade is important in Arizona even in spring time, and this stadium provides it.
There is also a large grass area in the outfield making it kid friendly. If your a parent like me you know how hard it is to keep a little one confined to a seat for three hours, so here is a tip...save some cash and sanity and just get lawn tickets and let your kid run around and be a kid. There is also a number of other activities for kid to do in the park, but they vary season to season so I can't tell you what they will be.
If you aren't a parent and you're looking for a more adult atmosphere try the Cubs or Giants facilities.
Prices for the games are on par with the other spring training stadiums in the valley of the sun, so no issues with that. Although, lawn seats are lower in price and not all stadiums offer that option. The food and beer are what is expected from a spring training facility, so nothing fancy.
Staff members are friendly and willing to help you with any questions that you might have. To sum everything up this place is great and kid friendly. Surprise Stadium is a possibly the best place to catch a spring training game in the west valley.
Also, parking is free along with the wifi!
